Worksheet: Osmotic Concentration
In this worksheet, we will practice describing how dissociation affects osmosis and converting osmotic pressures to molar concentrations.
A 0.010 M solution of the weak acid has an osmotic pressure of 0.293 atm at . A 0.010 M solution of the weak acid has an osmotic pressure of 0.345 atm under the same conditions. Each solution contains three dissolved species: the weak acid ( or ), the conjugate base ( or ), and the hydrogen ion (). The osmotic pressure of each solution is related to the solute concentrations in molar units.
Which acid has the larger equilibrium constant for ionization?
What is the equilibrium constant for the ionization of ?
